well then why didn't you ask that first instead of beating around the bush so to speak lol. No there not jewels, i guess there supposed to look like bubbles.
Somehow the jewelers can test. I take all my jewelry to have checked because some of the plated/filled turns my fingers, ears, wrists, ankles and neck green. For a long time I stuck with only solid gold! Now I love wearing my 925 solid silver jewelry! I can accessorize with my clothing and shoes! Sorry for rambling! :)
